those 305 heads will bump your compression and if you are willing to live with 5000rpms they will be good,match the ports to gaskets and clean up the pockets a bit,get some chevy brown valve springs(about 55bucks a set).these heads have 184in intakes and ports slightly smaller than stock 350, the combustion chambers should be around 60cc. these heads will build low end torque and will probably max out around 5 grand,the small chambers will give higher compression so watch your duration when picking your cam.when picking your cam keep these things in mind... power from idle to 5000,full duration around 262,moderate lift(440 to 460)and use small dia headders,500 to 600 cfm carb(smaller the better
